use HTTP::Tiny; use File::Listing qw(parse_dir); use File::Path; use File::Copy; use Archive::Extract; use Net::FTP; use Cwd; ###

I don't understand what the error message actually mean. I am running this script under our center cluster. Is there any missing modules (use HTTP::Tiny;) in my cluster? If that's the case, how can I installed the missing modules without being the root user?
